There is a tinfoil narrative that suggest that entire formats are in bed with intelligence services. It sounds pretty wild, but other zero-click attack vectors have been possible through sabotaging the parsing of file formats. ie. send a message -> hacked. How? the message wasnt even opened. How is, an app like Messenger receives a photo attachment binary, tries to unpack it and in doing so receives an instruction that stops the parser and executes arbitrary instructions.
